tempest - thanks for input. I've had some feedback that suggests the longer shaft, either 20" or 25". Do you have a suggestion on length and HP?
We're in a tough slip. Current is perpendicular to the keel at all times, depending on tide. To top it off we're novices.
Get the longest shaft you can find. Ours has an Evinrude Sail 9.9. It's very powerful when running on both cylinders but that's not often. But in even moderate seas the motor comes out of the water. It looks to have at least a 6" extension.
